Apart from the Learn Java app, what books and internet resources would any helpful person on this forum suggest to a college freshman(me) taking intro to CS, and struggling?
Right now, I'm struggling with writing my own for loops and nested for loops.
I'm really confused.
Usually, I'm very good coming up with solutions to analytical problems, but intro to CS is making me feel really dumb.
I sincerely need help.

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

Any rule of thumb for using switch vs if-else for performance reasons? Basically like let's say if you need to use switch case if there are more than 4 conditions?

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

hello every one
it is a usefull advice in learning this html course , leave html5 at the bigining & learn java script completly because in some sections (from 10/19 to end of the course) you need basic & even advance knowledge of JS . then your able to return to previous course & learn html5 easier.
goodluck.

I need to design a recursive function called replicate recur which will receive two arguments: times which is the number of times to repeat and data which is the number or string to be repeated.
The function should return an array containing repetitions of the data argument.
For instance, replicate_recur (3, 5) should return [5,5,5].
If the times argument is negative or zero, return an empty array. If the argument is invalid, raise ValueError.

i want to write a line of code that looks like this
if (a>10){
I know that in c++, you cannot just have greater than (>) or less than (<). j
it must be (>=) or (<=). But the code I need to write does not include the equal to(=). it just has to be greater than 10. What do I do?

so far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.

using a while loop create a guessing game program that keeps asking the user to enter a number until the user enters the number 7. You will need to create and initialise an int variable to zero. You can then use this variable as the condition in your while loop ( while the number is not equal to seven) Then in the while loop ask the user to enter a number and store the number entered in the number variable that is in the conditions of your loop.
